Sigma 2200i - Integrated Amplifier

Introduction

The Sigma 2200i is a powerful stereo integrated amplifier with features like USB and Network streaming, HDMI 2.0 switching and bass management to accommodate the evolving needs of a modern hi-fi system. It leverages the technical and performance advantages of our Sigma series separates to punch seriously above its weight class. As an integrated amplifier, the 2200i combines preamp and power amp functions in a single chassis. What’s special is its direct digital connection between the preamp section and the amplifier, which eliminates losses by removing digital-to-analog and analog-to-digital conversions from the signal path.

The preamp section of the 2200i features connectivity and circuit blocks found in the Delta series CP-800 and Sigma SSP. Inputs include fully balanced (XLR) and single-ended (RCA) analog with optional MM/MC phono, digital coax, optical, USB host and device, Ethernet for streaming and IP control and HDMI switching. Techniques like asynchronous synchronization and master clock mode allow us to manage the digital clocks for low jitter and high signal integrity. Analog sources are converted at 24/96 to preserve their original bandwidth and dynamic range.

Initial Installation

For the initial installation we refer you to pages 9, 10 and 11 of the Owner's Manual.

Extra considerations, based on Customer Service reports:

1. When first powering up the unit, check if the Firmware is Up-to-Date.

Press the Menu button the left of the Touchscreen, then press the STATUS button to check the current FW Version installed. On this Web Page, click on the "Latest Firmware" Tab to see if your unit has the latest FW.  If not download the firmware and follow the instructions.

2. Please do send in your Warranty Registration!

Sending in your Warranty Registration via our public website is the best way to ensure that we can reach you for product-related updates.

3. Start by programming your Speaker Configurations, then the Inputs.

Pages 22 to 24 of the Owner's Manual will give you the correct sequence of connecting all equipment.  

Many customers, however, stop there and do not take FULL advantage of the unit's powerful sound processing capabilities. By accurately programming your Speaker Configuration(s) your SSP will "know" how to correctly decode and process the incoming signal. In fact, you can create multiple Speaker Configurations and use them according to your Input sources: 5.1.2, 5.1 and Full Range Stereo are amongst the most important configurations.  See the Section below.

Once you have programmed your Speaker Configuration(s) you can set up your Inputs which will then allow you to "link" the Speaker Configurations to the Inputs and choose the default Processing Modes you would like to use.

Both the default Configuration as well as default Mode you programmed for a given Input can be overridden in Real Time, if you wish to do so.

Connection to Router

The Sigma SSP has an Ethernet port, capable of receiving incoming High Resolution Audio as well as communicating RS232 Automation Data.  Please follow the directives below for optimal use:

  • Use good quality CAT5 or CAT6 Ethernet cable;
  • Preferably, connect the Sigma SSP MkII directly to your Network Router;
  • Make sure the Router Ports mentioned below are open and accessible to the SSP MkII*);

*) Routers provided by Cable Companies or Internet Service Providers will auto-update from time to time, most often whilst you are asleep.  If the Sigma SSP starts acting up, then  the first thing to do is to see if the Router hasn't simply closed ports during the Auto-Update. The second measure is to reboot (power on/ power off) both the router as well as the Sigma SSP.

Required Router Ports

NOTE: CLASSÉ provided earlier information to "open" certain Router Ports.  This information has proven to be incorrect.

Instead, the CLASSÉ App and Router Problem that some customers experience can be explained by a lack of "UDP Multicast" support on certain routers. 

"UDP Multicast" is the protocol that the CLASSÉ App uses to communicate its data. We have noticed that certain Internet providers and Router manufacturers either:
- do not "switch on" this protocol by default (it must be activated)
- have stopped supporting it over the last decade.

Customers who experience CLASSÉ App functionality problems must check their routers for Multicast UDP functionality and support. If possible, it must be activated.  If Multicast UDP is not supported, the customer should check if another Router can be obtained, or see if a separate wireless router can be installed, one that does support Multicast UDP.


As far as the "Open Ports" is concerned: the list of Ports below is indeed correct. However, customers should NOT open these ports to the World Wide Web (Internet), but make sure these ports are accessible on the internal network (only).  Opening these ports to the outside world can pose an elevated security risk.

------

Make sure that the following ports are open on the Router. Without these ports, the unit will not perform its tasks.

Apple AirPlay/Bonjour (Music playback)

  • Port 554 TCP/UDP [Real Time Streaming Protocol]
  • Port 3689 TCP [Digital Audio Access Protocol]
  • Port 5353 UDP [Multicast DNS]

DLNA/UPnP (Music playback)

  • Port 1900 UDP
  • Port 5000 TCP

Classé App

  • Port 35295 UDP
  • Port 35296 UDP [Multicast]

TCP Control (RS232 Automation over IP, for Home Automation Systems like Crestron, SAVANT or Control 4)

  • Port 50001 TCP

Naming your unit

See Page 44 of the Owner's Manual.

We strongly suggest you give your unit a "Name" that will allow you to find it easily on your Home Network. In order to do this, you will need to read out the assigned IP-Address on the touchscreen, the type this IP address into a Web Browser on a computer (laptop, desktop) connected to the same network.  A Sigma SSP Web Page will appear, allowing you to change the name of the unit.

Static IP Address or assigned IP Address?

1. We suggest Owners who use the unit in a stand-alone setting, primarily for Network Audio Playback, to use the default setting (DHCP-assigned IP Address): The unit will get an IP Address assigned by the Home Router

2. For those Owners who use the Sigma SSP through Home Automation (e.g. Crestron, Control4, Savant), a fixed IP Address may be necessary.  See the instructions in the Owner's Manual. Once you have assigned a fixed IP Address, you will need to make sure that your Router respects this address. Depending on your Router, you may need to:

  • make sure that the fixed IP Address falls outside of the range of "Reserved IP Addresses" that DHCP will use;
  • make sure that the SSP's MAC Address is registered in the Router.  Since a SSP will not display its MAC Address on touchscreen, we suggest that you use an App like "Fing" to look up the SSP's MAC Address.

 

Home Automation

The Sigma 2200i can be controlled in a number of ways other than using the Front LED Button, the Touch Screen and the Classé App. the Rear Panel offers an IR-trigger input and output port and R232-Automation over IP via the Ethernet Port.

Factory Reset

A Factory Reset (called "Restore Defaults") erases all User Settings and resets the unit's parameters to Factory Default.  

A Factory Reset is useful when you want to program your unit from scratch, when you sell your unit to another customer or when your unit has unexpected behavior that may be related to conflicting settings.

Reset Procedure

NOTE:  The Reset Procedure will erase all your User Settings and cannot be undone. However, you can export your User Settings to a USB Key prior to Factory Reset. See the Tab "Export User Settings" for more information.

Procedure:

  • On the unit, press the MENU button located at the left of the touchscreen
  • Using the small black Classé Remote Control, press -- in sequence ---the buttons F1, F2, F3
  • You will now see the menu called "Other Options" (which we also call "Tech Menu") 
  • Press the button "Restore Defaults"
  • That's it.  The unit will reset itself and go into Standby

 

Voltage

  • All Sigma Series Products can operate on AC Voltages between 110V - 240V.  
  • Make sure to change the AC Fuse (rear) to match the AC Voltage of your country. 

When you change the fuse to accomodate a different AC Voltage, please contact Classé to obtain a new sticker for the back of your unit that indicates the new Operating Voltage. Without this, another user/customer might make a mistake in applying the correct AC Voltage and the Fuse may blow unexpectedly as a result

Fuse

  • Sigma Series components have one AC fuse accessible via the rear panel;
  • Make sure that the AC Fuse corresponds to the AC Voltage offered;
